New submission from Julien Palard:

Since the docsbuild-scripts [1] upgraded its sphinx-build [2], we're having this error when building the docs:

    ! Undefined control sequence.
    \py at authoraddress -> \strong

    {Python Software Foundation}\\ Email: \email {d...
    l.58 \sphinxtableofcontents
    !  ==> Fatal error occurred, no output PDF file produced!

it looks like to be from conf.py line 97 [3]:

conf.py-95-# Additional stuff for the LaTeX preamble.
conf.py-96-latex_elements['preamble'] = r'''
conf.py-98-  \strong{Python Software Foundation}\\
conf.py-99-  Email: \email{docs at python.org}
